There is a significant and independent positive relationship between serum cholesterol level and left ventricular mass in untreated hypertensive patients (particularly men), which may contribute to the prognostic value of left ventricular hypertrophy.

Supports hypothesis of cholesterol-LVH link in hypertension; leaves open causality and clinical relevance pending longitudinal data.
OBJECTIVE: To study the relationship between serum cholesterol level and left ventricular mass for a population of untreated hypertensive patients. DESIGN: A cross-sectional study. PATIENTS: We studied 273 untreated hypertensive patients without associated diseases consecutively referred for evaluation of blood pressure. All patients underwent M-mode echocardiographic assessment of left ventricular mass, office blood pressure measurement and 24 h ambulatory blood pressure monitoring. Fasting plasma glucose and total cholesterol levels were measured on the same day. RESULTS: We found a weak but significant correlation (r = 0.20-0.26, P < 0.01) between serum cholesterol level and left ventricular wall thickness or left ventricular mass irrespective of the mode of indexation used (height, height2.7 and body surface area). In multivariate analysis this relation remained significant after introduction of sex, age, weight, height, blood pressure and blood glucose level. When data for men and women were analysed separately the relationship between left ventricular mass and cholesterol remained significant for men only. CONCLUSION: There is a significant and independent positive relationship between serum cholesterol level and left ventricular mass that could contribute to the prognostic value of left ventricular hypertrophy.
